Barricade tape is brightly colored tape (often incorporating a two-tone pattern of alternating yellow-black or red-white stripes or the words "Caution" or "Danger" in prominent lettering) that is used to warn or catch the attention of passersby of an area or situation containing a possible hazard. It acts as a minor impediment to prevent accidental entrance to that area or situation and as a result enhances general safety. Barricade tape is also known as construction tape or barrier tape or in reference to the safety hazard involved as notice tape, caution tape, warning tape, danger tape or hazard tape. In case the tape is used by an organization the tape is named police tape, firefighter tape or traffic control device tape.

OSHA and ANSI provide precise specification for barricade tape colors.
These are found in OSHA regulations 1910.22 and 1910.144 and ANSI Z535.5-2007, Safety Tags and Barricade Tapes (for Temporary Hazards). However, the dimension, thickness, and materials of the barricade tape are left to the discretion of the manufacturer.
